The pressure sensors in mobile phones and accessories can be used in various use cases, such as to improve the activity

recognition tasks, ambient pressure monitoring, emergency E911 enablement, and automatic airplane mode.

PRESSURE SENSORS

The ST absolute digital output barometer integrates the consolidated pressure sensor in the new fully molded package to

further improve robustness, reliability, and moisture resistance, while reducing package thickness.

Waterproof pressure sensors are also available in the ST pressure sensor portfolio. They are resistant to chemicals like

chlorine, bromine, and salt water, as well as soaps and detergents. The LPS28DFW is an ultracompact piezoresistive

waterproof pressure sensor, which functions as a digital output barometer. Thanks to the dual fullscale (FS) mode, the device

provides wide coverage of both altimeter and water depth (up to 30 meters).

Another winning feature of the LPS28DFW is its lower power consumption and lower RMS noise. The LPS28DFW is the right

pressure sensor for delivering the high level of functionality users want and expect in personal electronics and consumer

applications.
